Validating with JavaScript

Is there a way to have the validation show on a JavaScript popup instead 
of on the header of the jsp?  I ask this a while back but I never got an 
answer.  

Thanks

RE: Validating with JavaScript

Not very elegant, but here ya go......

I did this with the intent of getting each error msg on a newline, but my
split("\n") is doing what I want so this should get you started....


<HTML>
<HEAD>
<TITLE></TITLE>
</HEAD>
<BODY>
Make sure you set errors.header and errors.footer to an empty string.  If
you use any html, it will show in your pop up box (quite ugly) unless you
filter it (you'll have to pay me to write that one for you;).
<br><br>
I hard-coded these for demonstration.
<div id="errors" style="display:none">
Password cannot be less than 3 characters.
Invalid username and/or password, please try again.
</div>

</BODY>
</HTML>
<SCRIPT LANGUAGE=javascript>
<!--

//********Warning, DHTML approaching **************
var divChar = "\n";
var errs = errors.innerHTML.split( divChar );
var txt = "";

for (var i=0; i < errs.length; i++)
{
    txt = txt + errs[i] + divChar;
}
alert(txt);

//-->
</SCRIPT>
